Microjob is a tiny TypeScript library that wraps Node.js worker_threads into a simple promise-based API for running CPU-bound work in background threads. It manages a worker pool with auto self-healing and supports both sync and async anonymous functions as jobs.

Use cases

• run heavy CPU computations off the Node.js event loop
• execute anonymous functions in worker threads
• parallelize CPU-bound tasks with a worker pool
• avoid blocking the main thread during intensive loops
• offload data crunching in a Node.js backend

When to choose

• you need simple, promise-based multithreading for CPU-bound work in Node.js
• you want a worker pool without managing worker_threads manually
• your jobs are short-lived anonymous functions

When to avoid

• your workload is I/O-bound rather than CPU-bound
• you need long-lived threads or shared state between workers
• you need to pass complex runtime context or non-serializable data to jobs
• you need a library with frequent updates or broad Node.js version support beyond 12+
